Sovereign Service and All American HVAC 6801 Oak Hall Lane, Columbia, MD 21045

"Great company to work with, great prices and reliability highly recommended"

"Prompt and thorough, multiple issues were found and fixed on site, same day. Mike took the time to answer my questions, and I couldn't be happier with how everything turned out."

"Best service"

"My A/C went out a few days ago and I needed it repaired ASAP, so I contacted Sovereign Service. Unlike other companies I've spoken with before, they were able to schedule a same-day appointment. While I was somewhat skeptical using a service with no reviews, it turned out to be a great experience. The owner, Chris, arrived at my house, replaced a faulty wire and an old compressor, and had the unit up and running in under 30 minutes. I chatted with him almost the entire time and not only was he friendly and polite, but was also eager to answer all of my questions. He also mentioned that he had over 30 years of experience in the industry, solidifying my decision to give them my business if I ever experience any more HVAC-related issues in the future. I highly recommend this company."
